Fluoroalkylphosphonic acid self-assembled monolayer gate dielectrics for threshold-voltage control in low-voltage organic thin-film transistors

Klaus Kern, Hagen Klauk, Frederik Sebastian Ante

An important prerequisite for the design of digital integrated circuits is the ability to control the threshold voltage of the individual transistors during manufacturing. To address the problem of controlling the threshold voltage of low-voltage organic t ...

Bias stress effect in low-voltage organic thin-film transistors

Klaus Kern, Hagen Klauk, Ralf Thomas Weitz

The bias stress effect in pentacene organic thin-film transistors has been investigated. The transistors utilize a thin gate dielectric based on an organic self-assembled monolayer and thus can be operated at low voltages. The bias stress-induced threshold ...
